Abstract (en)
A method of operating a hardware accelerator, includes loading a lookup table, mapping each of input data values of input data to an index of indexes in the lookup table based on an input data distribution of the input data, and obtaining output data values corresponding to the input data values using the lookup table. The output data values are proportional to corresponding softmax values of the input data values.
